Urban Clusters of Mumbai:

An Initiative to Make Affordable Housing Habitable

During the early 2000’s, Mumbai, India witnessed significant urban development accompanied by a massive influx of people seeking job opportunities. However, this population surge outpaced the existing urban infrastructure. Limited space and unaffordable housing forced many to inhabit informal settlements. In response, the government initiated the construction of numerous affordable housing complexes, aiming to reduce informal settlements and improve living conditions.

Unfortunately, a majority of these “Urban Clusters” lacked proper planning, resulting in the construction of residential units plagued by uninhabitable conditions. Issues such as insufficient sunlight, contaminated drinking water, hazardous locations, and a lack of community spaces disrupted the daily lives of residents. Consequently, many chose to remain in informal settlements, rendering these housing complexes largely vacant.

An architectural intervention is imperative to revitalize the existing infrastructure and enhance living conditions. This study delves into the causes and effects of the decline in these settlement spaces, analyzing the shortcomings in planning and design. The objective is to develop a design typology that addresses these issues, offering a sustainable solution to transform these housing clusters into viable, habitable spaces for the residents.

Mumbai: The City

Mumbai, often referred to as the “City of Dreams,” is a sprawling metropolis located on the west coast of India. It is not only the financial capital of the country but also one of the most populated and vibrant cities in the world. The urban development of Mumbai has been a fascinating and complex story, shaped by historical, economic, and social factors over several centuries.

By the mid-19th century, Mumbai transformed into a bustling city with significant industrial and commercial activity. The construction of railways in the 1850s further accelerated its development, linking the city to the hinterlands and enabling the movement of goods and people on a large scale. This period saw the emergence of distinct neighborhoods catering to different communities, such as Fort for the British administration, Girgaum for the local Marathi population, and Mazgaon for the dockworkers.

The 1960s and 70s marked a phase of significant industrialization, with Mumbai becoming a hub for manufacturing, finance, and entertainment. The city’s skyline began to transform with the construction of high-rise buildings, including residential towers and commercial complexes. However, these decades also witnessed growing disparities in wealth, with sprawling slums juxtaposed against affluent neighborhoods.

The 1980s and 90s presented new challenges for Mumbai’s urban development. The city continued to attract migrants seeking employment opportunities, which strained its infrastructure and public services. Inadequate housing and sanitation led to the proliferation of slums, which became a defining feature of Mumbai’s landscape. The rapid pace of construction often overlooked environmental concerns, resulting in pollution and congestion.

In recent years, Mumbai has witnessed a shift towards more comprehensive urban planning aimed at addressing its complex challenges. The Maharashtra government has implemented policies to promote affordable housing and upgrade infrastructure. Projects such as the Mumbai Metro and coastal road development aim to improve transportation and connectivity across the city.

Efforts are also underway to rehabilitate slum dwellers and create inclusive urban spaces. Organizations like the Slum Rehabilitation Authority (SRA) have played a crucial role in redeveloping slum areas while providing better housing options for residents. Additionally, initiatives like the Smart Cities Mission have focused on leveraging technology to enhance governance and quality of life in Mumbai.

Despite its economic dynamism, Mumbai faces persistent challenges related to housing, transportation, and environmental sustainability. The city’s infrastructure is often strained due to its dense population, leading to traffic congestion and overcrowded public spaces. Looking ahead, sustainable urban development will be crucial for Mumbai’s future growth. Balancing economic expansion with social equity and environmental stewardship will require innovative policies and investments.

In conclusion, Mumbai’s urban development is a story of transformation driven by historical legacies, economic opportunities, and demographic shifts. From its origins as a fishing village to its current status as a global metropolis, Mumbai continues to evolve, confronting both challenges and opportunities in its quest for sustainable development.

Mumbai: Affordable Housing

As one of the most densely populated cities in the world, Mumbai faces significant challenges in providing adequate and affordable housing for its residents, particularly low and middle-income groups. This publication will delve into the complexities of affordable housing in Mumbai, examining key factors, initiatives, and future prospects.

The primary challenge of affordable housing in Mumbai is the mismatch between demand and supply. The city’s population continues to grow rapidly due to migration from rural areas and other states, placing immense pressure on housing resources. This influx has led to the proliferation of informal settlements and slums, where a large segment of the population resides in substandard living conditions.

Land scarcity is another major constraint in Mumbai’s housing market. The city’s geographical constraints, coupled with stringent development regulations, have limited the availability of land for housing projects.

Recognizing the market potential and social impact of affordable housing, several private developers and real estate firms are venturing into this segment. These partnerships leverage the expertise of private developers with government support to deliver affordable housing solutions.

Some developers have also explored innovative construction techniques and designs to reduce costs without compromising on quality. Modular construction, prefabricated housing, and sustainable building materials are being adopted to make affordable housing more feasible and scalable.

Recognizing the urgency of the affordable housing crisis, both the central and state governments have introduced various initiatives to promote affordable housing in Mumbai.

1. Pradhan Mantri Awas Yojana (PMAY): This flagship scheme by the central government aims to provide affordable housing to urban poor households.

2. Slum Rehabilitation Authority (SRA): The SRA was established to rehabilitate slum dwellers by offering them alternative accommodation in high-rise buildings through the redevelopment of slum lands.

3. Rent Control Acts: Various rent control acts are in place to protect tenants from exorbitant rent hikes and eviction.

4. Affordable Housing Policy: The Maharashtra government has introduced policies to incentivize developers to invest in affordable housing projects.

Despite these initiatives, the supply of affordable housing remains insufficient to meet the growing demand in Mumbai. The complexity of land acquisition, regulatory hurdles, and financing constraints often impede the successful implementation of affordable housing projects.

Addressing the affordable housing crisis in Mumbai requires concerted efforts from policymakers, developers, and civil society. By adopting a holistic approach that combines regulatory reforms, innovative financing, and sustainable urban planning, Mumbai can aspire to provide dignified and affordable housing for all its residents, ensuring inclusive and equitable urban development.

Mumbai: Urban Clusters

Urban clusters in Mumbai represent a critical response to the city’s persistent housing crisis, aiming to address the acute shortage of affordable accommodation for its burgeoning population. While conceived with corruptive intentions, these urban clusters face a myriad of challenges that compromise their efficacy and impact on improving living conditions for residents.

The primary challenge confronting urban clusters is the lack of proper planning and design. Many of these settlements exhibit a dense and haphazard layout, characterized by narrow alleys and buildings constructed in close proximity to each other. This results in inadequate sunlight penetration and ventilation, contributing to a claustrophobic environment that negatively impacts the physical and mental well-being of residents. Moreover, the absence of green spaces and recreational amenities further diminishes the overall quality of life within these clusters.

Another significant issue plaguing urban clusters is the compromised access to essential services and infrastructure. Residents often grapple with irregular water supply, substandard sanitation facilities, and unreliable electricity connections. The provision of healthcare services is also suboptimal, exacerbating health risks and contributing to the prevalence of infectious diseases like tuberculosis among residents. Furthermore, the lack of proper waste management practices in these clusters leads to environmental pollution and health hazards, amplifying the already challenging living conditions.

In addition to infrastructural deficiencies, affordability remains a persistent obstacle for many residents of urban clusters. While these housing units are intended to cater to low-income families, the cost of ownership often exceeds their financial capacity due to escalating construction expenses and regulatory constraints. As a result, residents may resort to overcrowding within limited living spaces or seek alternative housing solutions, perpetuating the cycle of housing insecurity and informal settlements in the city.

Social isolation and community disintegration represent yet another challenge within urban clusters. The absence of communal spaces and recreational facilities diminishes opportunities for social interaction and collective engagement among residents. This isolation can foster feelings of alienation and detachment, undermining the development of a cohesive and supportive community within these settlements. Moreover, limited access to educational and vocational resources further constrains socioeconomic mobility for residents, perpetuating cycles of poverty and marginalization.

Despite the challenges and shortcomings associated with urban clusters, these settlements represent a critical component of Mumbai’s efforts to address the housing crisis and mitigate informal settlements.

Recognizing the multifaceted nature of these challenges is essential for implementing targeted interventions that prioritize the well-being and dignity of residents.

Unfolding: Disparities

The history of housing disparities in Mumbai dates back to the colonial era when the British administration implemented urban planning strategies that segregated communities based on race and socio-economic status. Areas such as Fort and Colaba were developed for the British elite, with spacious bungalows and wellmaintained infrastructure, while indigenous communities were confined to congested neighborhoods like Girgaum and Mazgaon. This spatial segregation laid the groundwork for enduring disparities in housing accessibility and quality.

After India gained independence in 1947, Mumbai experienced rapid urbanization driven by rural-to-urban migration and industrialization. The city’s population surged, leading to the emergence of informal settlements and slums as migrants settled in search of livelihood opportunities. The government’s focus on industrial growth often overlooked the need for affordable housing, exacerbating disparities between the wealthy and the urban poor. Informal housing clusters expanded rapidly, often lacking basic amenities and legal recognition.

The economic boom of the 1980s and 90s transformed Mumbai into a global financial hub, attracting investment and spurring real estate development. Luxury high-rises and commercial complexes proliferated, catering to affluent residents and corporate entities. Meanwhile, low-income communities continued to reside in precarious housing conditions, facing eviction threats and limited access to formal housing options. The widening income gap fueled by economic growth further deepened housing disparities in the city.

In response to the growing housing crisis, the government initiated slum rehabilitation programs aimed at improving living conditions for slum dwellers. The Slum Rehabilitation Authority (SRA) was established to facilitate the redevelopment of slum lands, offering alternative accommodation to eligible residents. While these initiatives sought to address housing disparities, challenges such as corruption, inadequate infrastructure, and resistance from local communities persisted, impacting the efficacy of slum rehabilitation efforts.

The legacy of housing policies in Mumbai reflects historical inequalities and policy decisions that have shaped the city’s socio-spatial landscape. Decades of neglect and inadequate urban planning have perpetuated disparities in housing access and quality. The persistence of informal settlements and slums underscores the enduring challenges of housing affordability and social exclusion faced by marginalized communities. Despite efforts to implement reforms and interventions, housing disparities remain a pressing issue rooted in Mumbai’s complex socio-economic history.

Unfolding: “Informal Settlements”

Mumbai is marked by the presence of numerous slums that reflect complex socio-economic realities and urban challenges. The origins of Mumbai’s slums can be traced back to the city’s rapid industrialization during the colonial era, which attracted migrants from rural areas in search of livelihood opportunities. Over time, the influx of migrants and the city’s limited land availability led to the emergence of informal settlements on the outskirts and peri-urban areas.

Mumbai’s geographical constraints, being a densely populated island city, have contributed significantly to the development of slums. The scarcity of affordable housing options has pushed low-income families towards informal settlements, where land is relatively cheaper but lacks basic amenities. This has resulted in extreme population density and overcrowding within slum areas, with families living in cramped dwellings and narrow lanes.

Slum residents in Mumbai often face challenges related to inadequate access to basic amenities such as clean water, sanitation, electricity, and healthcare. Many households rely on shared water taps and community toilets, which are insufficient to meet the needs of the population. Limited access to healthcare services further exacerbates health risks, contributing to the prevalence of communicable diseases in densely populated slum areas.

Many slum settlements in Mumbai exist in a state of legal ambiguity, with residents lacking secure land tenure rights. This uncertainty makes slum dwellers vulnerable to eviction and displacement, particularly when redevelopment projects or infrastructure developments encroach upon their settlements. The lack of formal recognition also hampers access to government services and development interventions, perpetuating the marginalization of slum communities.

Despite the challenges, slum communities in Mumbai exhibit remarkable traits. Residents often come together to address common issues through community-led initiatives such as cooperative housing societies, self-help groups, and micro-enterprises. These grassroots efforts highlight the agency and resourcefulness of slum residents in navigating adversity and striving for better living conditions.

Addressing the issue of slums requires a comprehensive approach that goes beyond housing to encompass urban governance, social inclusion, and economic empowerment. Effective urban planning, investment in infrastructure, and provision of basic services are essential to improving the quality of life for slum residents and fostering inclusive urban development in Mumbai.

Challenges: Unsanitary Living

The unsanitary living conditions prevalent in Urban Clusters in Mumbai pose significant health risks and challenges for residents, exacerbating the prevalence of infectious diseases such as tuberculosis (TB) and undermining overall well-being. Shockingly, statistics reveal that approximately 10% of residents in these complexes are affected by TB, a highly contagious respiratory disease. Even more concerning is the revelation that 60% of these TB cases were diagnosed after residents moved into their new homes within these Urban Clusters. This points to a disturbing trend where living conditions within the clusters contribute to the onset and spread of infectious diseases, highlighting the urgent need for improved sanitation and public health measures.

Furthermore, the lack of proper infrastructure and regulatory oversight is evidenced by the fact that in 2014, only 33.7% of all the units constructed in these Urban Clusters received occupation certificates. Despite the absence of official approval, residents were compelled to inhabit these substandard living spaces due to limited alternatives and the pressing need for housing in a city with housing shortages.

The unsatisfactory hygiene conditions within these Urban Clusters contribute to a host of health challenges beyond TB, affecting the overall quality of life for residents. Limited access to clean water and sanitation facilities leads to increased risks of waterborne illnesses and gastrointestinal infections. The disposal of solid and liquid waste in the absence of proper waste management systems further compounds environmental pollution and health hazards within the clusters.

The prevalence of TB and other infectious diseases within Urban Clusters underscores systemic shortcomings in public health infrastructure and housing policy implementation. The coexistence of overcrowding, inadequate ventilation, and poor sanitation exacerbates the transmission of infectious diseases, creating an environment conducive to health crises. These challenges are compounded by the lack of comprehensive urban planning and regulatory oversight, which perpetuates substandard living conditions and undermines residents’ fundamental rights to dignified housing and access to basic amenities.

Addressing the unsanitary living conditions in Urban Clusters requires a multifaceted approach that prioritizes public health interventions, sustainable urban development, and community empowerment. Investment in improved sanitation infrastructure, including clean water supply, sewage systems, and waste management facilities, is essential to mitigate health risks and promote residents’ well-being. Additionally, robust enforcement of housing regulations and quality standards is necessary to ensure the provision of safe and habitable living spaces for all residents. Collaborative efforts involving government agencies, community organizations, and civil society stakeholders are imperative to effect meaningful change and elevate the living conditions of those residing in these Urban Clusters.

44 Challenges

Challenges: Hazardous Locations

The unsanitary living conditions within Urban Clusters in Mumbai are exacerbated by their geographical proximity to environmental hazards, particularly along the banks of canals originating from the Deonar Dumping Ground, India’s largest dumpyard. Many of these Urban Clusters are situated in close proximity to these canals, which receive liquid waste discharge from the settlements themselves. This unfortunate cycle of environmental contamination contributes to the spread of fatal diseases such as Dengue and Malaria, posing significant health risks to residents.

The location of Urban Clusters along the banks of these canals underscores the broader challenges of environmental degradation and inadequate waste management practices in Mumbai. The canals, which extend up to 3 miles into the city, serve as receptacles for liquid waste from Urban Clusters, exacerbating pollution levels and creating breeding grounds for disease-carrying vectors like mosquitoes. This interplay between environmental pollution and public health underscores the urgent need for comprehensive interventions to address sanitation and waste management challenges in these areas.

The dumping of liquid waste into the canals not only compromises water quality but also perpetuates a cycle of environmental contamination that directly impacts the health and well-being of residents. Additionally, the lack of proper waste disposal infrastructure perpetuates the cycle of environmental degradation, further initiating health hazards within Urban Clusters.

The detrimental impact of unsanitary living conditions on public health highlights systemic challenges related to urban planning, waste management, and public health infrastructure in Mumbai. Addressing these challenges requires a holistic approach that integrates environmental sustainability, public health interventions, and community engagement. Investment in improved waste management systems, including proper sewage treatment and solid waste disposal facilities, is essential to mitigate the adverse effects of environmental pollution on residents’ health and well-being.

Furthermore, community awareness and empowerment are crucial components of sustainable solutions to improve living conditions within Urban Clusters. Engaging residents in waste reduction and recycling initiatives, coupled with the enforcement of regulatory standards for waste disposal, can contribute to long-term improvements in environmental quality and public health outcomes. Collaborative efforts between government agencies, community organizations, and civil society stakeholders are essential to effect positive change and ensure that Urban Clusters in Mumbai transition towards healthier, more sustainable living environments for all residents.

46 Challenges

Challenges: Overcrowding

The unsanitary living conditions within urban clusters in Mumbai are compounded by severe overcrowding and inadequate living space, where families of 2-3 individuals are forced to reside in extremely cramped quarters. The living space of 265 square feet for families in these spaces often translates to a highly congested and congested living environment, with little room for privacy or comfort. After accounting for essential amenities such as washrooms and necessary furniture, the actual usable square footage (USF) per individual dwindles to a mere 40 square feet, whereas the average USF globally ranges between 80-105 square feet.

The overcrowded living spaces contribute to a host of sanitation-related issues, including poor ventilation, limited air circulation, and difficulty maintaining basic hygiene standards. The close proximity of living quarters increases the risk of airborne diseases and the transmission of infections among residents. Furthermore, the lack of privacy and personal space undermines the physical and psychological well-being of individuals and families living in these confined environments.

In addition to overcrowding, the scarcity of usable living space within Urban Clusters impedes residents’ ability to maintain proper sanitation and hygiene practices. The cramped living quarters make it challenging to store and dispose of waste appropriately, contributing to environmental pollution and health hazards. The limited access to clean water and sanitation facilities further compounds hygiene challenges, increasing the vulnerability of residents to waterborne illnesses and communicable diseases.

Moreover, the substandard living conditions within urban clusters highlight systemic issues related to housing policy, urban planning, and equitable access to resources. The disparity between housing supply and demand exacerbates overcrowding and forces families into inadequate living spaces as a result of limited affordable housing options. Addressing these challenges requires holistic interventions that prioritize housing affordability, urban infrastructure development, and community empowerment to ensure dignified and sustainable living conditions for all residents.

Efforts to improve the sanitation and living conditions must involve comprehensive strategies that address the root causes of overcrowding and housing inadequacy. This includes investing in affordable housing solutions, expanding access to basic amenities such as clean water and sanitation facilities, and promoting community engagement in urban planning and development processes. By prioritizing the health and well-being of residents, housing organizations can work towards creating inclusive and resilient urban environments that foster dignity, equity, and quality of life for all individuals and families residing in urban clusters.

Challenges: Financial Instability

Financial instability is significantly impacted by the discrepancy between the affordability guidelines set by the Indian government for housing units and the actual cost imposed by regulations like those from MHADA (Maharashtra Housing and Area Development Authority). The government recommends that affordable housing units should ideally be priced at around four times the annual household income to ensure accessibility for low to middle-income families. However, due to the complexities of regulatory frameworks and market dynamics, the cost of these units often surpasses affordability thresholds. This mismatch forces many residents into precarious financial situations, where a substantial portion of their income is allocated towards housing expenses, leaving limited resources for other essential needs such as healthcare, education, and savings.

One of the contributing factors to financial instability is the imposition of lengthy lockin periods on buyers of Slum Rehabilitation Authority (SRA) flats. Initially set at a challenging 10 years, this lock-in period was eventually reduced to 3 years in 2015 following continuous public opposition and advocacy efforts. The extended lock-in period restrained residents from leveraging their housing assets for financial stability or investment opportunities, further exacerbating economic vulnerabilities within urban clusters. This regulatory burden not only affected individual households but also influenced broader economic dynamics within Mumbai’s urban fabric, hindering mobility and economic empowerment.

The consequences of these financial challenges are particularly acute within Mumbai’s urban clusters, where rapid urbanization and population growth intensify housing demand and strain existing infrastructure and services. The cost burden of housing, coupled with limited access to formal credit and financial services, creates a cycle of financial precarity for many urban residents. This situation is compounded by the lack of affordable rental options and the proliferation of informal settlements, which further restricts housing choices for low-income households and perpetuates economic instability.

Addressing financial instability within Mumbai’s urban clusters requires a multifaceted approach that combines policy interventions, regulatory reforms, and investments in affordable housing and infrastructure. Streamlining regulatory processes, promoting inclusive urban development, and fostering partnerships between public and private sectors are essential steps towards ensuring equitable access to affordable housing and enhancing economic resilience within urban communities. Additionally, expanding access to formal credit, financial literacy programs, and social safety nets can empower residents to navigate financial challenges and build sustainable livelihoods within the dynamic urban landscape of Mumbai.

Challenges: Unit Size

The small unit sizes prevalent in Urban Clusters developed under the Slum Rehabilitation Authority (SRA) in Mumbai pose significant challenges for residents, affecting both livability and overall quality of life. While these units comply with minimum size norms set by the SRA, these standards often fail to account for the actual number of people residing in the space and the essential habitable sizing required for adequate housing conditions. As a result, families are forced to cope with cramped living arrangements that do not meet their basic needs for comfort and privacy.

The design format of these units exacerbates the challenges associated with small living spaces. Many units lack exclusive rooms, resulting in all family members sharing a single common space for various activities such as sleeping, cooking, and socializing. This lack of privacy and separation of functions presents a significant challenge to livability, as residents struggle to maintain a sense of personal space and autonomy within the confines of their homes. The absence of distinct rooms further compromises residents’ ability to create functional living environments tailored to their individual and family needs.

Moreover, the cramped living conditions and absence of exclusive rooms contribute to heightened stress levels and interpersonal tensions among residents. The lack of privacy and personal space can strain familial relationships and negatively impact mental wellbeing. Additionally, the inability to designate specific areas for different activities hampers residents’ ability to maintain basic hygiene standards and organization within their living quarters.

The challenges posed by small unit sizes and shared living spaces highlight systemic issues related to urban housing policies and the prioritization of quantity over quality in housing development. The focus on meeting minimum size standards without considering the practical needs of residents perpetuates substandard living conditions and undermines efforts to promote dignified and sustainable housing solutions. Addressing these challenges requires a holistic approach that emphasizes the importance of adequate space allocation, functional design, and resident participation in shaping housing policies and development plans.

Efforts to improve the livability of small units within urban clusters should prioritize the adoption of housing norms that align with internationally recognized standards for habitable living spaces. This includes incorporating considerations for family size, spatial functionality, and privacy into housing design and development processes. Additionally, empowering residents through community engagement and participatory planning can ensure that housing solutions are responsive to the diverse needs and aspirations of Mumbai’s urban population. By promoting inclusive and sustainable housing practices, Mumbai can work towards creating equitable and resilient urban environments that prioritize the well-being and dignity of all residents living in urban clusters.

Challenges: Lack of Urban Planning

The planning of these Clusters prioritized maximizing Floor Area Ratio (FAR, FSI) without adequate consideration for setbacks between buildings. This approach results in densely packed structures with little to no space between them, creating a congested and potentially hazardous environment. The lack of setbacks not only compromises the aesthetic appeal of the area but also restricts air circulation and natural light penetration, contributing to a sense of claustrophobia and reduced livability for residents.

In contrast to other parts of Mumbai where there is a norm of providing a minimum of 15% open space of the entire lot size, SRA buildings often lack this requirement. The absence of sufficient open spaces within SRA complexes further exacerbates issues related to ventilation, thermal comfort, and overall quality of life. This oversight undermines the wellbeing of residents and limits opportunities for recreational activities or communal gatherings within the urban clusters.

The design flaws in SRA buildings pose serious safety risks, particularly in the event of a fire emergency. The lack of open spaces and setbacks means that there is limited escape routes and ventilation pathways for smoke to dissipate. This increases the likelihood of smoke inhalation and hampers evacuation efforts, putting residents at significant risk of injury or fatality during fire incidents. The absence of adequate fire safety measures underscores the urgent need for improved urban planning and building regulations to prioritize occupant safety and well-being.

Another critical issue arising from inadequate urban planning is the lack of accessibility for emergency vehicles within these complexes. Narrow passages and congested layouts impede the movement of ambulances and fire trucks, delaying emergency response times and potentially compromising medical treatment for residents in need. Instances where medical attention has not been provided on time highlight the urgent need for urban planners and authorities to prioritize infrastructure that enables swift and efficient emergency access, ensuring the safety and welfare of residents in urban clusters across Mumbai.

In summary, the lack of urban planning in Mumbai’s urban clusters, particularly in Slum Rehabilitation Authority (SRA) buildings, has led to a myriad of challenges including overcrowding, poor ventilation, inadequate open spaces, and compromised safety during emergencies. Addressing these issues requires a comprehensive approach that integrates urban design principles with stringent building regulations to prioritize public health, safety, and quality of life for all residents in urban environments.

Parity & Disparity: MHADA

The contrast between the approaches taken by MHADA (Maharashtra Housing and Area Development Authority) and SRA (Slum Rehabilitation Authority) in Mumbai underscores the importance of thoughtful urban planning and development strategies. MHADA’s focus on maintaining a Floor Area Ratio (FAR) of 1.7-1.9 reflects a commitment to sustainable urban growth and livability. This FAR range is considered ideal for Mumbai, striking a balance between population density and the provision of essential infrastructure and amenities. By adhering to these guidelines, MHADA has contributed to the creation of well-planned, affordable housing clusters that prioritize residents’ quality of life.

In contrast, the SRA’s utilization of a significantly higher FAR of 4.0 has led to various challenges and negative outcomes within Mumbai’s urban landscape. The implementation of SRA projects, marked by denser construction and higher population densities, has often resulted in overcrowded and poorly serviced neighborhoods. The reliance on a higher FAR without adequate investment in supporting infrastructure has strained public resources and diminished the overall livability of these areas. This approach highlights the pitfalls of prioritizing quantity over quality in urban development initiatives.

Prior to the introduction of SRA projects, Mumbai witnessed the successful development of affordable housing clusters under MHADA’s initiatives. These projects embraced urban planning best practices, including the allocation of open spaces and the promotion of publicprivate partnerships to ensure ongoing maintenance and upkeep of buildings and surroundings. By integrating these measures, MHADA fostered sustainable communities where residents felt a sense of ownership and belonging.

The success of MHADA’s initiatives underscores the importance of balanced urban development strategies that prioritize livability and community well-being. By adopting lower FARs and investing in essential infrastructure and amenities, MHADA has demonstrated a commitment to creating vibrant, sustainable neighborhoods that enhance residents’ quality of life. Moving forward, it is essential for urban planners and policymakers to learn from these experiences and prioritize holistic approaches to housing and urban development that prioritize the long-term well-being of Mumbai’s diverse communities.

Design: Context

Urban Clusters grapple with a myriad of challenges that impact residents’ quality of life and overall well-being. One of the pressing issues is the affordability crisis in housing, exacerbated by discrepancies between government guidelines and actual housing. This discrepancy often leaves many households spending a significant portion of their income on housing, limiting resources for other essential needs such as healthcare, education, and savings.

Moreover, the implementation of lengthy lockin periods for buyers of Slum Rehabilitation Authority (SRA) flats has hindered residents’ ability to leverage their housing assets for financial stability or investment opportunities. This regulatory burden has contributed to economic vulnerabilities within these urban clusters, impacting mobility and economic empowerment.

Additionally, the high FAR utilized by some developments, such as those under the SRA, has led to overcrowding, strain on infrastructure, and diminished livability. The focus on quantity over quality in urban development initiatives has resulted in poorly serviced neighborhoods and limited access to essential amenities.

Furthermore, the lack of green spaces and inadequate pedestrian infrastructure has compromised air quality and overall environmental health within these urban clusters. The absence of community-oriented design elements, such as ground-floor retail spaces and communal areas, has hindered social interactions and the formation of strong neighborhood bonds.

In response to these challenges, my design aims to alleviate the issues faced by Urban Clusters By prioritizing affordability and sustainable urban planning principles, my design will focus on creating well-planned housing complexes that integrate open spaces, greenery, and pedestrian-friendly infrastructure. The incorporation of ground-floor retail spaces will promote economic activity and enhance social interactions, fostering a sense of community and belonging among residents.

Additionally, my design will emphasize the importance of public-private partnerships to ensure effective maintenance and management of public spaces and amenities. By engaging stakeholders from various sectors, including residents, local businesses, and government agencies, my design seeks to establish collaborative efforts aimed at enhancing the overall quality of life within these urban clusters.

Rethinking the internal layouts of apartments within Urban Clusters presents a compelling challenge, given the existing constraints and shortcomings faced by residents. One of the predominant issues revolves around the housing units built under the SRA guidelines, which prioritize minimum sizes without considering the actual needs and comfort of residents. This oversight results in cramped living conditions that lack adequate space and privacy for families, exacerbating issues related to livability and well-being.

To address these challenges while retaining the existing density within the urban clusters, a strategic typological solution is proposed to reconfigure internal layouts. The aim is to optimize space utilization, enhance privacy, and improve overall living conditions for residents. Central to this solution is the creation of exclusive rooms within each unit, ensuring that family members have designated spaces for rest, study, and personal activities. By introducing partitions and reconfiguring interior walls, each room can be tailored to accommodate specific needs while maintaining a sense of openness and accessibility.

Moreover, the redesigned internal layouts prioritize natural light and ventilation, addressing critical aspects of habitability and comfort. Strategic placement of windows and ventilation openings optimizes airflow and daylight penetration, minimizing reliance on artificial lighting and improving indoor air quality. This not only enhances the living experience but also contributes to energy efficiency and environmental sustainability within the urban clusters.

Additionally, the reconfigured layouts prioritize accessibility and safety with shorter, open internal corridors that facilitate better circulation, particularly in emergencies. Dedicated spaces within units cater to diverse age groups and activities, promoting holistic well-being and intergenerational harmony.

Importantly, the proposed solution empowers residents to participate actively in transforming their living spaces. By allowing individuals to demolish and restructure interior walls with minimal resettlement, the process becomes inclusive and adaptive to residents’ preferences and needs, minimizing disruption and preserving community continuity. This approach has the potential to catalyze positive change and contribute to the sustainable transformation of urban living.

Children took matters into their own hands and asked young grownups to help them clean and level grounds so that they could play

Activists and NGOs such as Yuva and Habitat for Humanity joined hands in creating better facilities for people

Due to the pressure of the users, two mini parks were developed within the site which improved things on a surface level

Medical assistance was provided and a small community space was built for children to study

People are waiting for an urban intervention which would alleviate their actual challenges which affect the lives of 24,000 residents on a daily basis

these housing clusters into viable, habitable spaces for the residents.

2030

Due to the Cluster being semi-vacant, there is no loss of density even after demolishing 40% of the structures

Users have better living conditions on the unit level, urban level and the ecological level

Carrying the same sense of social cohesion, the clusters also provide spaces for the neighboring informal settlements to integrate into the Cluster

There is a provision for better access for pedestrains as well as emergency vehicles

Children can go to the school right at the centre of the Cluster without their parents have to worry about their travel

Habitants in and around the site can easily access government provided healthcare services near the site for free which will improve living conditions

Children will have independent spaces to study and elders will have their own space to rest and recover

Street connectivity increases social interaction and hotspots act as the epicenters of activity which can host weekend markets, events, festivals and bring in a new sense of engagement for outsiders as well

This typological situation will act as an example for all other Clusters in the city and affordable housing developments throughout the globe
